My late model A is leaking engine oil from the front of the fan shaft right behind the belt pulley. Im wondering if there is supposed to be a lot of oil in the shaft housing. I know there is a felt seal behind pulley. Any help would be appreciated.
I just rebuilt 2 of these. Deere sometimes used the inside of the fan shaft to carry the oil vapors back to the intake. On others there is an additional tube that does the same thing. If yours is the first type, there can be oil if enough pressure builds up in the engine and blows enough oil up there along with the vapors..
However, my first thought is that your bearing is heating up and melting your grease and that is what is running out.
My JD 1250 has oil leaking out of a small hole on the back of the base collar of the shift lever. The other lever has the same hole built in. Attached is a photo of it, and a short video of the oil sort of spewing out.
